WRAPPING-MACHINE.

Specification of Letters Patent.

Patented May 18, 1920.

Application filed December 10. 1918. Serial No. 266,114.

To all whom it may concern:

Be it known that I, WVILLIAM B. MUNN, a citizen of the United States ofAmerica, residing at Memphis, in the county of Shelby and State ofTennessee, have invented'certain new and useful Improvements inVVrapping-Machines, of which the following is a specification.

The present invention relates to an improved wrapping machine, designedparticu larly for use in wrapping or packaging collars and cuffs in thelaundry, but adaptable of course for use in other connections and forother purposes, as will readily be understood. For convenience ofdescription, however, the invention in the present instance will bereferred to as a collar and cuff packaging or wrapping machine,preferably operated manually, and designed to build up a uniformlycylindrical bundle or package of laundried cuffs or collars, having theends of the paper wrapper tucked in at both ends of the package, andpresenting a neat and attractive bundle as to its shape and appeara-nce.

The invention consists essentially in the utilization of a fixedreceptacle having a movable bottom upon which the collars to be wrappedare placed, and in certain novel combinations and arrangements of partswhereby the size of the paper sheet required is gaged, and particularlyin combining with the movablebottom of the receptacle, means forimparting friction whereby the bottom is free to be pulled up, but mustbe pushed downwardly, all as will hereinafter appear more specifically'In the accompanying drawings one complete example of the physicalembodiment of the invention is illustrated, constructed and arrangedaccording to the best mode so far devised for the practical applicationof the principles of the invention.

In the drawings 2 Y Figure 1 is a perspective view showing the machinecomplete, and illustrating also in connection therewitha paper cutterand a tagging or labeling device for the completed showing details ofconstructionof the rer'ocablerplunge rlo 'o'r stern.

ceptacle, its movable bottom, and the lifting and lowering means for thebottom.

Fig. 5 is a sectional View taken at line 55 of Fig. 3.

Fig. 6 is an edge view showing the friction device for retarding thedownward movement of the plunger rod that supports the movable bottom orplunger head. Fig. i is a side view, as seen from the right in Fig. 8 isa vertical sectional view of" the friction device or retarder.

1 Fig. 9 is a top view of the device as in In the preferred embodimentof the invention as illustrated in the drawings, the machine is adaptedfor manual operation and is depicted as supported upon a table 1 incombination with the frame 2 which supports the paper roll 3 from whichthe wrapping paper for the bundle is to be taken.

The paper from the roll passes over guide rolls 3 and is out by areciprocable cutter 4 slidable on the guide rod 5 and provided with arotary cutting knife 6 that travels in the groove 7 of the ifixed bar 8supported in the frame 2. The sheet of wrapping paper is drawn from the'roll 3, by hand, and the required length of paper is cut from the rollby manual manipulation of the slidable cutter, and then this sheet ofout paper is wrapped about the receptacle 9 in which the collars andcuffs are piled or stored preliminary to wrapping them.

The receptacle is preferably of metal, cylindrical in shape to conformto the collars, and of suitable dimensions to receive the collars intheir normal condition, as indicated by dotted lines in Fig. 2, whereinthe paper wrapper is also indicated by dotted lines.

The receptacle 9 hasan open top to receive the collars and cuffs, but isfashioned with a closed bottom 10, except for the central orifice 11therein, and by means of the flange 12, exterior of the receptacle andWithin the receptacle the vertically rec'p 14, which forms the movablebottom of the receptacle, are operable, the bottom fitting neatly withinthe interior of the cylindrical receptacle, and the stem 13 passingfreely,

.but not too loosely through the opening 11 in the bottom plate 10 ofthe receptacle. The movement of the stem and bottom is guided andrendered stable by the utilization of three vertical guide rods 15 thatare connected at their lower ends beneath the table top 1, by the spiderframe 16, and a threaded extension bar 17 of the stem also is fixed atthe center of the spider, clamping nuts 18 being provided to make a firmjoint. These three rods and the spider form a guide frame that iscompleted by the upper flanged ring 19 which surrounds the receptacleabove the table and to which the rods are rigidly fastened as seen inFig. 3. From this description it will readily be seen that the stem,spider, guide rods, and ring 19 form a movable guide frame for thebottom 14 of the receptacle, and as the rods pass through small openings20 in the bottom plate 10 of the receptacle the stability of the frameis enhanced so that these parts may be lifted or depressed withoutwabbling. Usually the movable bottom is manipulated manually by graspingthe ring 19 in the hand, and thus the bottom may be freely liftedthrough the co-action of the frame, but preferably the lowering movementof the bottom is to be retarded, and as a matter of fact, the movementis stopped, and the movable bottom held in position by means of afriction device co-acting with the stem, so that the bottom may not belowered without power being applied, preferably by hand on the ring 19,as will be described.

In connection with the movable ring 19, a paper or wrapper retainingdevice is utilized, which includes a pair of parallel rollers 21 movablein a vertical plane with the ring 19, and supported from the ring by anarm 22 pivoted at 23 in the ears 24 on the ring and a spring 25, betweenlugs of the arm and the ring, holds the rollers 21 against the paperthat is wrapped about the receptacle. Thus the paper sheet is cut fromthe roll and wrapped about the receptacle, the size of the sheet beingdetermined by the eye of the operator. It will be noted that, in theirfixed relation, the bottom 14 is above the ring 19, so that when thebottom edge of the paper sheet is brought down to the ring 19 and thesheet wrapped about the receptacle, the upper edge of the sheet projectsabove the upper edge of the receptacle, and the lower edge of the sheetis below the bottom of the package that is to be formed on the movablebottom, thus providing upper and lower edges of the wrapper that may betucked in when the bundle is complete.

The retarding or friction device for the stem is located just beneaththe bottom plate of the receptacle in an opening in the table top, andcomprises a housing 26 preferably of cast metal in U-shape, in which arelocated the two friction blocks 27 and 28. These blocks lie parallelwith the stem 13 diametrically opposite each other and have leatherfacing strips 29 at their inner faces frictionally engaging the stem 13.The friction block 28 is held in adjusted and fixed relation with thestem by a set screw 30 which bears against the block and is threaded inthe housing, but the friction block 27 is designed togrip the stem, orbe released therefrom, the former, action for the purpose of retardingdownward movement of the stem or actual holding of the stem, and thelatter condition to permit the lifting, by free motion, of the stem andmovable bottom. To this end the block 27 has a cam notch 31 cut in itsouter edge, and within the cam notch a roller 32 is located, a lightspring 27 being used for holding the block 27 against the roller 32 tohold the stem from dropping, but permit the stem to be moved or pusheddown by hand pressure on the ring 19.

The housing 26 is suspended beneath the 9 table top by its brackets 33that are pivoted at 34 to the bracket arms 35 of the bottom plate of thereceptacle, and a spring 17 coiled about the stem acts as a cushionagainst the bottom of the housing when the bottom 14 is lifted.

On the stem 36 in Fig. 1 a spool 37 may be retained to provideconvenient cord for tying the completed bundle, and at 38 in Fig. 1 apaper tape holder for gummed tapeis indicated for customary use.
